Climate change is implicated in poleward shifts in the distributions of species

"Climate
change is expected to result in climatic zones moving poleward and an
associated shift in the geographic ranges of bird species. Evidence for
such shifts is now becoming apparent. It remains difficult to causally
link such distributional shifts specifically to climate change as a wide
range of additional factors also influence species distributions.
However, thanks to recent research in Europe and North America, a
remarkably consistent pattern is emerging that provides compelling
evidence that climate change is responsible for significant northward
shifts in the distribution of avian communities across the northern
hemisphere." See: http://www.birdlife.org/datazone/sowb/casestudy/171
